T-Cell Therapy (EB103) in Adults With Relapsed/Refractory B-Cell Non-Hodgkin's Lymphoma (NHL)
(STARLIGHT-1)
What this study is about
This is an where both patients and doctors know the treatment given, gradually increasing doses, multi-center, Phase I/II clinical trial to assess the safety of an autologous T-cell therapy (EB103) and to determine the Recommended Phase II Dose (RP2D) in adult subjects (≥ 18 years of age) who have relapsed/refractory (R/R) B-cell NHL.
View original scientific description
This is an open-label, dose escalation, multi-center, Phase I/II clinical trial to assess the safety of an autologous T-cell therapy (EB103) and to determine the Recommended Phase II Dose (RP2D) in adult subjects (≥ 18 years of age) who have relapsed/refractory (R/R) B-cell NHL. The study will include a dose escalation phase followed by an expansion phase.
Interventions
BIOLOGICAL
EB103
EB103 is an autologous T-cell therapy whereby a subject's own T cells are transduced with a lentiviral vector expressing the EB103 transgene.
Primary outcome measures
To assess the safety and tolerability of EB103.
Time frame: Up to 2 years (active assessment period); additional long-term follow-up (LTFU) up to 15 years
Type, frequency, and severity of adverse events (AEs), including treatment-emergent AEs (TEAEs), treatment-related AEs (TRAEs), serious adverse events (SAEs), adverse events of special interest (AESIs), clinically significant laboratory abnormalities recorded as AEs, and AEs leading to permanent discontinuation.
To determine the Recommended Phase II Dose (RP2D) of EB103 (in Phase 1, Dose Escalation)
Time frame: Time Frame: 16 months
RP2D based on maximum tolerated dose (MTD) (if reached), overall safety, preliminary efficacy, and manufacturing capability.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Age 18 years or older at the time of informed consent
- Histologically confirmed R/R B-cell non-Hodgkin's lymphoma (NHL)
- Adequate organ function
- Relapsed or refractory (R/R) disease defined as ONE OR MORE of the following:
- R/R after ≥ 2 lines of systemic therapy
- For the following NHL types: Burkitt lymphoma, Precursor B-cell lymphoblastic lymphoma, or Mantle cell lymphoma: R/R after ≥ 1 lines of systemic therapy
- Disease progression or recurrence ≤ 12 months after autologous hematopoietic stem cell transplantation (HSCT)
- For subjects who are considered transplant-ineligible: progressive disease as best response after ≥ 4 cycles of first-line therapy and stable disease as best response after ≥ 2 cycles of second-line (salvage) therapy; subject must have received an anti-CD20 monoclonal antibody and an anthracycline as one of their qualifying regimens
- All subjects must have received an appropriate chemoimmunotherapy regimen which at a minimum includes an:
- Anti-CD20 monoclonal antibody AND
- An anthracycline-containing chemotherapy regimen
- Positron emission tomography (PET)-positive disease according to Cheson 2014
- Eastern Cooperative Oncology Group (ECOG) ≤ 2
- Toxicities due to prior therapy must be stable and recovered to Grade 1 or less
Exclusion criteria
- Prior CD19-targeted cellular therapy
- History of Richter's transformation of chronic lymphocytic leukemia (CLL)
- History of another primary malignancy that has not been in remission for ≥ 2 years.
- History or presence of clinically relevant Central Nervous System (CNS) pathology
- CNS disease which is progressing on most recent therapy or with a parenchymal mass which is likely to cause clinical symptoms
- Subjects with active cardiac lymphoma involvement which is not responding to treatment
- History of myocardial infarction, cardiac angioplasty and stenting, unstable angina, or other clinically significant cardiac disease within 6 months of informed consent
- Active, uncontrolled systemic bacterial, fungal, or viral infection. Patients with HIV, hepatitis B, or hepatitis C are eligible provided their infection is being treated and the viral load is controlled.
- History of autoimmune disease resulting in end organ injury or requiring systemic immunosuppression/systemic disease modifying agents within the last 2 years
- History of severe, immediate hypersensitivity reaction to any agents used in this study, including the conditioning chemotherapeutic agents
- Venous thrombosis or embolism not managed on a stable regimen of anticoagulation
- Autologous HSCT within 3 months of informed consent
- Subjects with a prior allogeneic transplant at least 6 months prior to study enrollment are eligible unless experienced graft-versus-host disease (GvHD) that requires ongoing treatment with systemic steroids or other systemic GvHD therapy, such as a calcineurin inhibitor, within 12 weeks of initial screening
- Live vaccine within 3 months prior to planned start of conditioning regimen

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
